EXCLUSIVE: Kirstie Alley makes a rare appearance in public as she attends a street barbecue with her young grandson. The 66-year-old former Cheers star star was seen at the outdoor picnic with 10-month-old Waylon Tripp Parker, born last June 21 to Kirstie’s adopted son William True Stevenson. The party was thrown in a suburb of Clearwater, Florida, which is home to the Church of Scientology, of which Kirstie is a member. According to reports in the National Enquirer, the star signed autographs for fans on a 1980 booklet called ‘The Way To Happiness’ written by Scientology founder and science fiction author L. Ron Hubbard. Kirstie’s rep reportedly denied that the picnic was a church event. 22 Apr 2017 Pictured: Kirstie Alley. Photo credit: AMI/MEGA TheMegaAgency.com +1 888 505 6342
